Alternative systems of broiler chicken farming, including organic farming, represent an important segment of meat production, partly due to increasing consumer awareness of animal welfare, traceability, and farming practices. These systems are becoming more popular as complementary activities on farms. In this thesis, we evaluated whether pasture-based organic chicken farming is a suitable activity for our farm. The aim was to assess the technological requirements of pasture-based production, develop a plan for converting the existing barn and designing mobile housing units, and formulate balanced feed mixtures using home-grown or purchased organic feed ingredients. The study is based on a review of relevant scientific literature and the practical implementation of a pilot rearing trial involving 100 Prelux-Bro broiler chickens, reared for 81 days using a combination of indoor brooding and subsequent free-range production. Feeding followed a three-phase program (starter, grower, finisher), with feed mixtures formulated according to nutritional recommendations. The results indicated that, with appropriate microclimatic conditions, pasture management, and feeding strategies tailored to the animals’ physiological requirements, it is possible to ensure high standards of animal welfare and satisfactory productive performance even during extended fattening periods. The use of the slow-growing Prelux-Bro genotype proved suitable for outdoor production systems. Based on the analysis, organic pasture -based broiler production was assessed as a technically feasible and economically viable complementary activity for our farm.
